AN'rrsKrn nnvioni pplicatin filed December 1 To all 'who/mit may concern.:

Be it known thatl, JOHN THOMAS Plinn, a citizen of the United States, residing at 1183 Avoca Avenue city of Pasadena, in the county of Los ngeles and State of California, have invented a new vand useful `Anti- 4skid Device, of which the following is a speciication.

An object of this invention isv to provide a cheap, simpleand effective device for preventing automobiles from skidding. v Y

A further object is" to provide a device of this character which can be applied to an automobile with 'maximum ease and expedition, so that when occasion to supply Vthe wheels with the anti-skiddevice; arises, as in the case of a sudden storni that makes the Y road slippery, the driver can apply the de` vice in a few moments and can, afterwards,V at' pleasure, quickly removethe saine. y I have discovered that in order toprevent the wheels of an automobile from skidding, it is unnecessary that the anti-skid device shall extend entirely around the periphery of the wheel as inpractice heretofore, and a feature of this invention is the provision of a short patch-like arrangement attached to the wheel and covering` only a comparatively small portion of the wheel and separated from any other anti-skid device by a space not less than that equal to one-quarter of the circumference of the wheel; and in actual practice'l prefer to apply not more than two yof such devices to any one wheel, thus economizing without loss of efficiency; and I find also that by fitting each of two or more wheels ofthe vehicle with only one non-'skid device, perfect security against skidding is provided for. It may sometimes be found desirable to apply the anti-skid device to all four wheels ofthe vehicle and `in suchcase only one anti-skid device need be applied to any one wheel. K ,Y

Where two of the devices are applied to a single wheel, as showninFig. l wherein the second patch on each'of the wheels exposed to view is indicated by dottedlineathey will be diametrically opposite each other, 'and if forl any reason four' anti-skid devices, not shown, should be applied to one wheel they would be applied equidistant from each other. v

A further object of the invention is to provide a cheap, strong, anti-skid device for pneumatic tires.

A distinct novelty and object of my inveny tion is also to provide such an anti-skid device with auxiliary anti-skidmeans that are quickly and easily attached to, and quickly and easily detached from, the device, said auxiliary means, when required, being removable and exchangeable without necessitating theremoval of the Vdevice from, or the looseningof the device on,fthe, periphery of the wheel, and, in one form of the invention` serving as lmeans whereby the main antif skid means are detachably fastened toy the device, so that, if said latter means have been worn beyond effective usage, they, too, may

be reinovedandexchanged without necessitating removal or loosening ofthe device.

Further objects, advantages and ,features 1 of invention kmay appear vfrom the accom-- panying-v drawings, the'subjoined detail descrip tion and the appended claims. l

The accompanying drawing illustrates the invention.

Figure l isa diagrammatic view of an autoinobile provided with an anti-skid device n in accordance with this invention.

Fig. 2 a fragmental side view of a wheel provided with my anti-skid'device.

Fig. 3 is an enlarged fragmental section on y line w3, Fig. 2. 4

The backing 1 is preferably made of sole leather and is of such a length `as to allow it to be wrapped far' enough around the pneumatic tire 2 to cover the portion of the pneumatic tire that is subject to contact with the road for the width of thepatch. It may extend about ail'the way across the space between the opposite sides of the wheel rini 3. i

Said backing isprovided on opposite sides of its center and at equal distances from'the ends respectively, with slotsetthrough which a fiexible connection'as the strap 5, having fastening means asv the buckle 6 is inserted. Saidfbacking is provided on its outer face with nonskid projectionswhich may be of various forms asis indicated in the various views. ln Fig thereA arev shown adjacentto the slots .il bolts 7, having heads 8 intermediate the'folds 9, viOfof a reinforcement on the inner side of the backing. Such reinforcement may be, and is shown as, folded; the bolt 7 being inserted through the outer band 9, and its head is covered over by the inner band l() of the reinforcement, so that the head of the boltwill not work any destruction to the walls of the pneumatic tire f in Figs. 2 and 3 the bolt ible backing adapted taclied to Vthe Wheel of a vehicle;- anti-skid 2. The inner band l may, and is shown as extending upwardly and the strap passes therethrough, thereby insuring the reinforcement being held in place. Nuts l1are screwed tightly onto said bolt on the outside o-fthe backing.

In the form shown in Figs. 2 and 3, the nuts 7 clamp end links 13 of chains 14 that extend across the tread ofthe tire and constitute the anti-skid means that contact with the street surface when the tire is under ordinary load.

Under heavy loads or-With a flattened tire, the nuts 11 may also engage the track or road surface and thus serve as anti-skid means auxiliary to the projections 12 or the chains lli.

To apply the device tothe Wheel it is only necessary to bend the sole leather piece 1 on the surface of the tire adjacent a spoke 15, and'then Wrap the strap 5 around said Spoke and secure it by the buckle 6.

I find in actual practice that a comparatively slight fastening such asis indicated in the drawings by the `strap 5 and buckle 6 is suiiicient to hold the backing in place,`rfor the reason that the friction of the inside of the backin uponthe strap 5 and upon the rubber of tie tire is sufficient, hold the device from matic tire 2. n

From the foregoing description itisreadily seen that I have produced an exceedingly simple, convenient and time-saving antislipping on the'pneuskid device, particularly because the nuts 11,

being quickly and easily attached to the bolts 7 and also quickly and easily detached therefrom, are quickly and easily attached to, and quickly and easily detached from, the patch 1, and therefore, Whenever required can be removed and exchanged Without ne'- cessitating the removal of the patch from, or the loosening of the patch on, the tire`2, and because in the form of my invention shovvn and nut connections serve as means for detachably fastening the antiskid chains 14: tothe patch 1 and thereby also dispense with the necessity of removing the patch from, or loosening the patch on, the tire, Whenever it is required to removethe chains and to exchange them.

I claim:

1. An anti-skid device comprising a iiexto be removably atchains adapted to be removablv attached on the outside of said backing; a flexibleconunder load, to f easily and quickly of the backing when attacher? to the periphery of the wheel, and a, reinforcement fastened to and betweensaid nutand bolt connections to avoid destructionofa tire on said Wheel.

2- A11 anti-Skid attachment, comprising a flexible backing; iiexible means-adapted to removably vattach of a vehicle; antifskid devices arranged on one side of said backing; a reinforcement on thc other side Vof, saidv backinggg,'attachingA means extending through said backing` an one end'ofisaid reinforcement for removably attachingsaid anti-skid devices to` said backing, whereby said anti-skid devices may be easily and quickly attachedV to orremoved rom said backing Whilev said 'backing is held on the periphery of saidxvlieel'; andthe other eiidlof said reinforcement being folded over the attached attaching meansv for the purpose` set forth. 3. An anti-skid attachment, comprising a flexible backing, flexible means adapted to removably attach said backing to a Wheel of a vehicle;4 anti-skid devices arranged on one side of said backing; a reinforcement on the other side of said backing;

one end of said' reinforcement for attaching said anti-skiddevicesto inggvhereby said removably said backantieskid devices may be attached: to f or removed fromsaidjbacking Whilesaid patch is held on the periphery of4 said Wheel; and the other end of sadireinforcement .being folded over the attached ,endf thereof and V said` attaching means for the purpose setcfOlthnnd extends upwardly and aroundjsaid flexiblefmeans so` p as to be held in place.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this th day of December 1917. v I
